测定并分析了４种状况下远红外干燥箱体内各处温度、物料水分的差异。结果表明箱体内各点的温度和物料水分含量并不相同，循环风机工作或和排湿风机联合工作时均匀性较好。 The differences of temperature and material moisture in the far-infrared oven under four different conditions were measured and analyzed. The results show that the temperature inside the box and the moisture content of the material is not the same, circulating fan or exhaust fan work well with the uniformity of the better.
